McStas - A neutron ray-trace simulation package
|
| The plot shows the intensity of scattered neutrons (red is
highest intensity). The sample is at the center of the sphere with the
neutron beam coming from the left. Clearly seen is the shadowing effect
of the sample causing a lower intensity opposite the beam. Also seen is
the effect of the non-symmetric geometry of the sample, causing lower intensity
directly above and to the side of the sample. |

May 9th: Vacancy at the ESS DMSC as scientific software developer
The interim ESS DMSC (Data Management and Software Center for the European Spallation Source) located at the Niels Bohr Institute, University of Copenhagen is seeking a candidate for scientific software development within areas of data analysis and simulation. More specifically, the work is oriented toward integration of the McStas and Mantid software packages.
The advert is available through this link.
For further questions or enquiries, please contact Prof. Stig Skelboe, Niels Bohr Institute, University of Copenhagen, skelboe@nbi.dk, phone +45 35321449
March 12th: Respin of McStas 1.12c dmg for OS X Lion
As reported to mcstas-users@mcstas.org, the McStas 1.12c dmg for OS X Lion was unfortunately corrupt. A new version of the image has been uploaded. The filename is slightly different to be able to distinguish the image from older downloads you may have.
February 1st: Various bugs and workarounds
A couple of annoyances have been reported, here they are plus relevant workarounds:
- 1.12c version of SNS_source.comp crashes on Windows systems. A functional version has been uploaded to the share. Thanks to Ruep Lechner for reporting the bug and to Garrett Granroth for providing a fixed component.
- The previously released updated dmg image for Mac OS X should really only be used on Lion, not Snow Leopard, that is use this image on Lion and this image on older releases.
- On (at least some) Mac systems, it seems Virtual_output.comp should not be used with type="double" or "float". The workaround for the time being is to use the default "text" format instead. The issue seems to become more severe if large ncounts are used.
January 6th: New affiliation for Erik Knudsen and Peter Willendrup
A reorganisation at DTU and RISØ DTU has resulted in a new home for the DTU effort on McStas, namely DTU Physics.
Hence, Erik Knudsen and Peter Willendrup have a new affiliation, see the Contact page.
At our new home we will be part of a dedicated neutron- and X-ray scattering group, which we think will become a very good home!
